@ -173,6 +173,11 @@ parsed as 64 bit signed integer. The sum of data length in the
following DATA frames must match with the number in "Content-Length"
header field if it is present (this does not include padding bytes).
RFC 7230 says that server must not send "Content-Length" in any
response with 1xx, and 204 status code. It also says that
"Content-Length" is not allowed in any response with 200 status code
to a CONNECT request. nghttp2 enforces them as well.
Any deviation results in stream error of type PROTOCOL_ERROR. If
error is found in PUSH_PROMISE frame, stream error is raised against
promised stream.
